1'0 ILZZ '/,v7tcnt 'zit 71ml/ concern:

Be 1t known that l, OLE 0. KrTTLEsoN, a citizen of the United States, residing at Lee,

in the county of Dekalb and State of Illinois, have invented a new and useful Lubricator,

of which the following is a specification.

This invention relates to improvements'in force-feed lubricators of that type disclosed vin Patent No, 648,386, dated May 1, 1900,

and now owned by me. i

@ne of the objects of the invention is to provide improved means that 'is exceedingly simple and effective for detachin'g the plunger from the driving mechanism when abnormal'resistance to the movement of said plunger is occasioned through any cause, thus permitting the continued movement of said driving mechanism without the-o eration of the Iplunger and `avoiding the iability of brea age.

A further and important object is to proe vide novel means ofa simple nature that will effect the stoppage o theplunger and the de' tachment thereof from the driving Imechanism when the same has reached the limit of its movement, said means ermitting the ready return of the plunger or the purpose of supplying the lubricator -with a fresh charge of lubricant and feeding the same therefrom.

The preferred embodiment of the invention. is i lustrated in the accompanying drawings, wherein- Figure 1 is a side elevation ofthe lubricator. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical sectional view. Fig. 4 is a detail sectional view on the line 4 4 of Fig. 2. Fig, 5 is a detail vertical sectional view showF ing the relation of the parts when the driving mechanism is disconnected from the plunger.

Similar reference-numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrateda receptacle-body is employed that is in the form of a tubular body 6, having ears 7 at its lower end by means of which the lubricator can be secured upon a support. Extending from the lower portion of the body is a supplypipe 8, and located on one sido of the upper portion of said body is a receiving funnel or spout 9, communicating with the upper portion of the interior of the rece tacle, The said recep tacle constitutes a older for the lubricant. Slidably mounted in the receptacle is a plun* ger. 10, that is movable ,from a position above the inlet 9 to a position in the lower portion of the receptacle, its downward movement `being limited by a suitable stop e-bolt 11,

screwed into the under side ,of said plunger. A. stein l2 is si/viveled, as shown at 13, in the upper ortion ofthe plunger and extends througlli3 the receptacle above the top of the same. rlhis stem has a threaded engagement, as shown at 111, with a cap 15, that iits in the open top of the rece tacle and is secured against movement y .suitable setscrews 16. v

l Mounted upon the cap 15 is a wormwheel 17, constituting a driving device, said wormwheel having a hub 18, provided with ya central bore 19, that loosely receives the stem 12, satl lstem being thus slidable through the wheel and said wheel being rotatable upon the stem. Under normal conditions,y however, ythe wheel is held against rotationabout.

the stem by means of a dog 20, pivoted upon the, hub of the wheel, the inner end 21 of said dog engaging in longitudinal slot or keyway 22, formed in one side of the stem, the outer' end of the dog being weighted. A handle 23 is carried by the wheel. l Located intheupper ortion of the keyway is a pair of 24,v

the ower end of the lower lugconstitutlng a shoulder 25, ada )ted to abut against the' mner end 21 of t e dog, as `hereinafter describedthe upper end 26 of the upper lug constituting a supportingeshoulder, as is also hereinafter set forth.

Located upon one si( e of the upper portion of the receptacle or holder are spaced brackets 27, terminating in ournal-bearings 28, throu lh which passes a driving-shaft 29.

Loosey journaled upon the shaft between the bearings is a worm 30, that'meshes with the worm-wheel 17. @ne end of the worm is provided with sockets 31, in which is engaged the projecting ends of a pin 32, carried by the shaft, said pin and sockets thus constituting a clutch connection between the shaft and worm. The said. clutch connection is yieldingly maintained by means of a spring 33, coiled upon the shaft and bearing at its inner end against the end of the worm opposite that having the sockets and passingthrough the adjacentbearing 28. The inner end of this spring is oHset, as shown at 34, and rests upon the adjacent bracket 27, whereby said spring is held against rotation. The oute; end of said spring is borne 'a ainst by one of a pair of jam-nuts 3,5, threa ed upon the end of theshaftoutsidefkthe adjacent bearing, said IDO 5 5 about the steinwithout moving kWorm 30, and consequently y and said shaft will rotate without imparting shoulder 26, thereupon, said inner end of the v will act as a Wedge. Conso strike the inner end 21 of the dog,

nuts thus constituting means for varying the tension of the spring. Secured to the opposite end of the shaft and outside the opposite bearing is a ratchet-wheel 36, and loosely jurnaled on said end of the shaft directly adi' jacent to the ratchet-wheel is an arm 37, havl ing a spring-pressed dog 38 engaging the teeth of said wheel.` 1 In use the arm 87 is connected to a suitable moving part of the engine that will effect the. `l oscillation of said arm, and the supply-pipe l leads to the part to be lubricated. Assuming, therefore, that the plunger is in i-ts highest l, position, it will be apparent that4 lubricant l may be poured into the receptacle through l the spout 9. The oscillation of the arm 37 l will cause the intermittent rotation ofthe ratchet-Wheel, thus revolving the shaft, the the worin-Wheel If the dog is'engaged in the keyivay, it Will be evident that the stem Will also be rotated,and thus threaded downward through the stationary cap 15, which constitutes a supporting device. The plun er will therefore be moved downwardly' and the lubricant beneath the sume expelled through the delivery-pipe 8. Af ,lff, however, there should be any abnormal resistance to the movement of the i `ffor instance, by the failure of the. lubricant to pass through the pipethe worm- Wheel will be brought to a standstill and the Wormoperating upon the stationary teeth uently said worm will be moved longitudinal y of the shaft 29 against the tension. of the spring 33. Said worin will thus be unclutched from the shaft any movementto the gearing and the plunger. The breakage of parts is thus avoided. When in working condition, however, the spring no t only maintains the Worm clutched to the shaft, but being stationary acts brake to prohibit the retrograde movement of the Worm, shaft, and ratchet-Wheel with the return ofthe' arm and dog, so that said dog will always ride over the teeth of the ratchetwheel when operating in one direction. As the plunger approaches its lowermost position the shoulder of the lower lug 24 will and conseuently saiddogwill be swung until it is en tirely disengaged from the keyvvay, as illustrated in Fig. 5. Thereupon the v/ormwheel will be unlocked'from the stesi, and said wheel tvill consequently rotate freely the same and without affecting the plunger. lt will therefore be seen that the plunger is automatically stopped in a predetermined position. To return the plunger to its original position above the feed-spou;t,it is onl necessary te elevate the Worm-Wheel until tlie inner' end-2i of the. dog 20 will reengage the keyway above the dogwill rest upon said shoulder, supporting the wheel out of ,enga ement with the Worm. By turning said Whee through the medium of the handle, the plunger can be readily elevated, and after having been returned to a proper position about` the feed-spout 'the wheel disengaged and dropped, so that it is again in engaged inthe keyway. The receptacle is then :filled and the lubricator ready for action.

From the foregoing it is thought that the construction, operation, and many advan-` tages of the herein-described invention will' against relative movement andp'ermitti'ng- .the sliding movement of the stem through the device, and means for automaticallyop: crating the dog to disengage the stem an driving device to permit the rotation of 'the latter with respect to the former when said stem has reached a predetermined position.
